Frequently asked questions

Loan-to-cost (LTC) and loan-to-value (LTV) are financial ratios used in real estate to determine the loan amount a lender is willing to provide to a borrower.

Loan-to-cost (LTC) refers to the ratio of the loan amount requested and the total cost of the real estate project, including the cost of acquiring or renovating the property. For example, if a real estate project costs $100,000 and the borrower requests a loan for $80,000, the LTC ratio would be 80%.

Loan-to-value (LTV) refers to the ratio of the loan amount requested and the property's appraised value after rehab is completed, also known as ARV. For example, if the appraised value of a property is $100,000 and the borrower requests a loan for $80,000, the LTV ratio would be 80%.

We typically use these ratios to determine the risk involved in a loan and to set loan terms, interest rates, and other conditions. Borrowers with a lower LTC or LTV ratio are considered less risky and may be offered lower interest rates or more favorable loan terms.

In Georgia, mortgages are rarely used. A security deed (deed to secure debt) is the customary security instrument in Georgia. It's a three-party instrument that includes the borrower, the lender, and a neutral third party called a trustee.

When the borrower fails to repay the loan, the trustee has the authority to sell the property to repay the loan. This security instrument is commonly used in Georgia as an alternative to a mortgage.

BRRRR is a real estate investment strategy for "Buy, Rehab, Rent, Refinance, and Repeat."

This strategy involves buying a property, making repairs and improvements to increase its value, renting it out to tenants, refinancing the property to pull out cash, and then repeating the process with a new property.

BRRRR aims to increase investors' cash flow, build wealth through appreciation, and generate passive income through rental properties.

An interest-only loan is one in which the borrower pays only the interest for a set period before being required to start paying down the loan's principal.

For example, you take out a $100,000 interest-only loan with a 5-year term and an interest rate of 5%. During the first five years, you would only be required to pay $250 a month (5% of $100,000), which would go toward paying the interest on the loan. After five years, you would start paying the interest and a portion of the principal, which would be a higher monthly payment.

Interest-only loans are often used in real estate for flipping properties or temporary cash flow needs. However, because the borrower isn't paying down the principal, these loans tend to have higher rates and can result in much higher overall interest charges over the life of the loan.
